Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The motor driven plow forming the subject matter of the presentinvention comprises a supporting frame or truck includl ing upper andlower side bars 5 and 6, preferably formed of angle iron, connected byspaced uprights 7 to which are bolted or otherwise rigidly securedspaced transverse bars 8. The supporting frame or truck is provided witha detachable extension 9 on which are pivotally mounted the .steeringwheels 10, said extension being provided with rearwardly inclined braces11 having their upper ends connected toupri-ghts 12, similar inconstruction to the uprights 7, the extensionformino' a continuation ofthe main frame of the truck when in use.

Journaled in suitable bearings 13 onthe lower side bars ofthe truck, isa rear axle 14 carrying spaced traction wheels 15. Each tra tion Wheel15 is provided with a sprocket wh el 16 over which extends a sprocketchain 17 leading to a `relatively small sprocket, wheel--18mounted on-'astub shaft 19. Resting on the lower side bars of the truck, is aplatform-2O having a seat 21 secured thereto and provided with anupwardly Iand rearwardly extendin plate 22 l which forms a guard for thetraction wheels,

15, as best shown in Fig. 1 of the drawings. Mounted on the platform 20,is an engine uor=other suitable motor 23, the driving shaft 24 of whichextends ytransversely of the truck A and is vprovided with terminalpulleys 25 and 26. Slidably mounted on each end of the drivingshaft 24,is a sleeve 27 having a gear wheel 28 secured thereto which meshes witha similar gear wheel 29 secured to the V adjacent stub shaft 19 so thatwhen the driving shaft 24: is rotated, motion will 'be transmittedthrough the gearing to the tratinv -wheels to driye the machinevinaforwardV direction.. Each sleeve 27 is provided with a connecting bar30 which encircles the adjacent stub shaft 19`and on which is mount- (eda pinion'31, which latter meshes with a pinion 32 carried by the sleeveso that by operating the shipper lever 33 the gear w eel 28 may belmovedout' of engagement with "the wheel 29 and the jpinion 3l moved.

into meshtherewith so as to cause the machine to travel in a rearwarddirection, when desired. ne end of each sleeve 27 terminates in a clutchmember 34 for'engagement with a correspondingclutch member 35, thelatter being secured toand movable with a lever 36, by operating which,motion may be transmitted from the engine to the traction wheels ortheshaft 24 allowed to rotate' withoutai'ecting the machine. Thus itwill be seen that by'manipulating the levers 33 upper end thereof ispivotally connected at 44l to a relatively short link 42suspended from abar or rod 43 extending transversely. -of the truck frame in advance ofthe traction wheels, fas best shown in Fig. 2 of the drawings."l T econnecting links 42 are pivotally' mounte on the rod or bar 43 and areadjustable laterally thereon so as to permit the plows, 3 7 to becentered'with respect to` the-truck frameor moved laterally toeithei`side thereof as the case may be, said links being supported in adjustedposition by means of screws or other clamping devices,

:indicated at 44. f

Secured` to the extension 9 of the truck frame, is a transverse draftbar 45 to which are secured plurality of spaced hooks 46. each hookreceiving a draft chain 47 leading to the 'adjacent 'plow beam, asshown. 1t

will here be .noted that by reason of thev pivotal connections 39, 41and-42, the plows are free to move forwardly and upwardly so as toconform to any irregularities in the' 'surface soil over which themachine is trav'- eling. It will also be noted that the plows' aremovable Iindependently of each other so thatJshould one of the plowsstrike an obstruction in the path of movement of the h truck, the otherplows will not be as tfected. Moreover, this manner of suspending' orhanging the plows from the-truck frame permits the .plows to pass overhilly gr rolllng groundv and produce an even furrow of vtion of the plowv be regulated at will.

preferably disposed one slightly belts 63 tothe pulleys 55,

contour of the soil.

Depending/from "each, plow beam 40, is

.a caster wheel 48, the shank of which is provided with a plurality ofopenings 49 adapted to receive a pin or similar fastening 'device 50 sothat by placing said pin 50 inthe different openings 49, the depth ofpenetrapoint into the soil may As a means for' successively raising andIlowering the`plows sa as to leave the ends of the furrows in transversealinelnent at the'opposite ends or sides of a field, or whentransporting :the truck from one place to another, there are provided aplurality of winding drums l51 mounted for rotation on a stationaryshaft 5,2, each drum being provided at one end thereof with a ratchethead 53, which opera-tes in a casing 54, vand at its other end with apulley 55. Connecting the guard ianges 56 of eachm'inding drum, is a pin57Mto which is secured the adjacent end of a cord, chain or otherflexible medium 58, the other end of 'said cord or chain beingfastenedto an eye 59 secured to the upper longitudinal edge of the adjacent plowbeam at a point slightly in advance of the pivot 39,. as best shown inFig. 4 of the drawings.

i The stationary shaft 52 is rigidly secured to the luprights 12 of thetruck extension,

.and disposed inra plane slightly below and in advance of`thezstationary'shaft 52 is .a rotating shaft 60, the latterbeing'journaled in suitable brackets 61 also carried by the truckextension 9. Keyed or otherwise rigidly secured to the rotating shaft60, are a plurality of wheels or pulleys 62yover which extendendlessvbelts 63 leading, to and encircling the adjacent pulleys y onthe stationary shaft 52. Secured to one end ofl the shaft 60, is a beltulley 64 over which extends a belt 65 lea ing to the belt pulley 25 onthe driving shaft 24, so that when the shaft 24 isrotated, motion willbe transmitted through the medium of the belt 65 to the pulleys ,62 andthence through the .thereby to wind the co ds 58 on the drums y5,1andJe'ect the raising of the plows. A clutchl 66 'isalso preferablymounted on the platform to permit the belt pulley 25 to be thrown into`and yoke or hanger being- .pulley 62 so as to permit the" idle pulley 1.

brackets are in turn mounted on and adjust` -able longitudinally of abar 77 connecting the upper sills 5 of the truck frame. Thus,

it will be seen that by exerting a downward pull on any one of thelfinger rings 7 5, the idle pulley 71 will be moved into engagement withthe adjacent belt 63 so`as to .tighten the belt and thus cause motion tobe transmitted from the rotating. shaft 60 to the adjacent drum toeffect the raising of i the plows.

The casing of each winding drum is provided with a tubular extension 78in which is slidably mounted a locking rod 79, the free end 80 of whichis inclined or beveled l for engagement with the teeth on 4the ratchethead '53'so that after the winding drum has been rotated to effect theelevation of the plow, the locking rd 79 willautomatically engage theteeth on the ratchet head and thus lock or hold the plow in ele- .vatedposition. @ne end of each. locking rod vis provided with a collar 81against which bears a coiled spring 82, which spring also bears againstthe end of the adjacent tubular member. 78 'and serves to normally andyieldably hold the activeA or pointed end 8O of the adjacent locking rodin engagement with the teeth on the` ratchet head.. j

The locking yrods 79 are pivotally connected at '83 with suitable handoperated levers 84: depending from the bar 77' so that vby pressingrearwardly on 'the free ends ofV the levers 84, the rods 79 may bedisengaged from the ratchet heads 53 so as to permit the plows to returnb y their own weight to lowered position.v As' soon as the levers 84 arereleased, however, the springs 82 will automatically cause the rods toengage the ratchet heads and prevent further rotation of the `windingdrums. ln this manner, the plows may be supported in any desiredposition of vertical adjustment. It will of course be understood thatthe inclined or' beveled ends of the locking rods 7 9 Jare so disposedas to permit winding of the cords or cables on the drums, but willprevent reverse movement rof said .drums when the locking-rods are inengagement with the ratchet' heads.

The levers 814C, as well as the casings 5d, are preferably V'adjustabletransversely of position 4by screwsor similar fastening de.-

driver or operator of the machine may cony veniently manipulate thevarious levers and finger rings without the necessity of leaving hisseat.

Secured to the forward longitudinal edgev of the platform20, are aplurality of relatively small rollers 86 which bear against the adjacentcords or chains 58 and serve to prevent abrasion or injury thereto whenXraising and lowering the plows. A steering head 87 is also preferablydisposed near the operators seat 21 and connected with a transverseshaft 88 to which are secured spaced chains 89 leading to the steeringwheels 10 so that the truck may be guided in the usual manner.interposed between the traction wheels 15, is a cylindrical pulverizing.drum .or packer, said drum or packer being preferably formed insectionsQO detachably united and each provided with inwardly extendingbraces 91, the converging ends of which are bolted together to -forin aboxing 92 adapted to turn on the rear axle of the truck. Each v sectionof the cylindrical drum or packer is lpprovided with a plurality of ribs93 which serve to crush or pulverize the soil, there being traction lugs94 formed on the ribs in order to prevent slipping thereof. The sections90 of the drum or packer are so arranged that they may` occupy only aportion of the` space between the tractiony wheels, or may extend fromone traction wheel to the other, the end sections fitting over thetraction wheels..

used in theu gang, the sections of the drum or packer will terminateshort of one of the Ltraction wheels,.as shown in Fig. 1, and .thusallowl the traction wheel having no packer section secured thereto, tektravel on the unplowed ground. This' Aconstruction also permits thegroundto be plowed close toad fence or away from the fence, as desire In Extending transversely of the truck frame I verizer', is a rod 95 towhi are secured a plurality of s acedscraping ives or fend-- ers 96,which latter operate between the 'pul verizing ribs 93 and serve toprevent dirt adhering to the packer nand thus clogging or otherwiseobstructing the same. rllhe rod at the rear of thecombinedker and pul-95 is also provided with'spaced hooks 97 from which are Xpreferablysuspended one or lmore disk harrows, indicated at 98. Ar-

sou

When' only three plows are 'ranged at the rear of the disk harrows 98,`

are drag harrows 99, each provided with a yoke or bail 100 whichprojects forwardly f for attachment tothe adjacent hook 97.

As a means for raising andlowering the thetruck frame and are held inadjusted ydiskharrow 98, 'there is provided a suitable operating cord101, one endof which plows are successively cessively 4extends over apulley l102 'and is proricled withV a fingerl piece 103, while the otherend thereof is-,provided with an extra strand, whichstrands pass over asheave or pulley 104 for attachment to the disk harrow 98, and arethence extendedY upwardly and fastened over hook 105; Thus .it will be,seen that byexerting a downward pull on the finger piece 103, the diskharrow'9'8 may be raised and lowered, at-will. Simjilar ropes or cablesform a connection be-l tween the drag harrow 99 and a correspondingfinger `Aring 106, preferably arranged at the front of the truck nearthe ring 103. Thus it will be seen vthat as the machine is caused totravel ina forward direction over a field-o15 other iclosure, the plowswill' turn the4 soil, while the drum will pulverize and pack the soiland the members 98 and.99 disk and drag the same, thus placing the soilin condition for planting. Instarting to plow a field, one of the plowsis allowed to enter the soil, while the other two are elevated. Asthesmachine travels in a forward direction, the elevated allowed( todrop so that theyl will enter the ground in transverse alinement withthe furrow .formed by the first mentioned plow, and conversely, at theend of the field,- the plows are su'celevated by means of the windingdrumsso that `the machine leaves all of the furrows in predeterminedtransverse .|alinement, as twill be readily understood.

`WhenL itis desired to use the machine as .a grain drill, drag harrows.are substituted for the gang plows and the grain drill' is supported onthe truck frame in rear ofI the packer and pulverizer which, in thisinstance, is assembled so as to entirely fillvv the space between thetraction 7wheels. The grain drill will be operatively connectedI withthe traction wheels 'bysuitable gearlng machine,

`By ,dismantling the machine, that is to say, by removing thegrotmd-treating iin-i." plem'ents, as well as the raising and loweringmechanism, and setting the front axle and steering wheels "back to aposition beneath the platform 20, the machine may be used withogoodcresults as a traction engine for general, farm use.

When this# device is Iasa traction engine, the pulley 26 mfy beconnected through the medium of a belt with a thresh-` separator orother machinery for drivingf.\ the same. rlfhe machine is preferablyprovided with a suitable cover 146 which serves to house and protect the:oper.

ating mechanism ofthe machine, as best shown in Fig. 2 of the drawings.

It will of course be understood that any vdesired number of plows may bemountedy on the machine and the relative disposition vof the severalparts, as well as the size and Having thus-'described the invention,what is claimed as new is: 1. An agricultural machinetincluding awheeled truck, a rod extending transversely of the truck, a linkpivotally' mounted on the rod,'a plow, an arm having its upper endpivoted to the lower end of said link and its lower yend pivoted to theplow, means operatively connected with the low ad-l jacent said 'arm andextending orwardly therefrom for raising and lowering the latter, andmeans for supporting the plow in different positions of verticaladjustment.
